METHOD FOR PERFORMANCE CHARACTERISTICS RESTORATION OF MACHINE PARTS Russian patent published in 1994 - IPC

Abstract RU 2009269 C1

FIELD: mechanical engineering. SUBSTANCE: method for performance characteristics restoration of machine parts includes removing of a surface layer by powerful ion beam having nanosecond-class pulse duration, energy-flux density 1-10 J/cm2, and pulse quantity ranging from 1 to 10; and vacuum annealing at a temperature equal to the detail operation temperature for 0.1-2 hours. The method of the invention may be used for repair of articles which operate for a long time under heavy loads and high temperature in hostile environment. EFFECT: increased efficiency of operation. 3 dwg, 2 tbl
